Unit 6: Light Waves
Chapter 2: Light as a wave
Lesson 2.4: Explaining Sunlight and Skin Cancer
Goal:
- Show what happens to genetic material when it is exposed to different types of light from the sun.
Do:
Use the Light Waves Simulation to test the effects of different types of light from the sun on genetic material. Refer to the image above to see which types of light from the sun reach Earth’s surface. Turn Show Energy on.
- Drag GENETIC MATERIAL to a platform in the testing area.
- Set the light source to CUSTOM and turn on the light.
- Use the slider to change the wavelength/type of light the laser emits. Test:
- Ultraviolet (UV)
- Visible (any color)
- Infrared (IR)
- Microwave
- Radio
- Record the results on your Modeling Tool: Investigating Light’s Effect on Genetic Material sheet.
- If the type of light has an effect on genetic material, record it.
- If the type of light has no effect on genetic material, record it.
